I used to play LEGO Harry Potter long time back (5-6 years), took couple years break and again got addicted to Lego Jurrasic word last year. Its all individual choice, what I like .. you might not. So just pick any

Between these two... I would choose Lego Harry Potter. The game of my childhood. I played it again recently that inspired me to collect Lego. I even ordered Hogwarts set. Thankfully, there was a seller who could ship to St. Louis easily and cheap.
